Title: Method of producing an underground tunnel structure
Inventor: PAUSE HANS DIPL ING
IPC: E21D11/10
Filed: 1982-05-18
Abstract: The invention relates to a method of producing an underground tunnel structure, in particular a traffic tunnel, with any tunnel cross-section which is produced by means of a shield tunnelling machine or a cutter shield and which is provided during the progress of the work with inner formwork for section-by-section production of the concrete supporting arch. To be able to dispense with additional measures for absorbing the driving forces for the shield tunnelling machine or a cutter shield, the pressing forces from the shield driving are transmitted directly to the fresh concrete of the supporting-arch section produced last. Here, a powerful pressure is exerted on the fresh concrete, the excess water in the fresh concrete is separated and prompt hardening of the concrete is achieved, the separated excess water being drawn off from the inner formwork via drainable filter elements.

Title: Castor for furniture, appliances and similar objects
Inventor: SCHROEDER DIETER
IPC: B60B33/00
Filed: 1982-05-29
Abstract: The subject matter of the invention is a castor for furniture, appliances and similar objects having at least one single-row roller bearing and at least two bearing components which bear the roller bodies. The invention proposes on the one hand that all the bearing parts should be produced from plastic and that the latter, including the roller bodies, should be connected rotatably to one another in the manner of an axially fixed plug-in locking element. According to a further embodiment of the invention, a fork-shaped bearing component is provided in whose web a non-circular opening is punched, the edge of which, which is partially bent over, partially flared out, serves as a locking counterbearing for a bearing component-side extension provided with barb-like locks so that in a simple manner the entire bearing can be connected by plugging to the bearing part without tools and without securing means and can be easily released again when appropriate.

Filed: 1982-06-12
Abstract: Gegenstand der Erfindung ist ein elektronisches Parallel-Addier-Subtrahierwerk, das pro Dekade nur einen dualen Tetraden-Addierer-Subtrahierer aufweist. Diese Vereinfachung wird dadurch erzielt, daß in jeder Dekade ein Speicher-Flip-Flop (6) angeordnet ist, das bei H-Potential am Ausgang (y) rechtsseitig angesteuert wird, wenn die Leitung (c) kurzzeitig H-Potential hat. Damit hat der Ausgang dieses Speicher-Flip-Flops dauernd H-Potential, wodurch in der zweiten Hälfte dieser Ansteuerung nach Figur 8 noch die Zahl 6 (LHHL) hinzuaddiert wird, wenn dieses Addier-Subtrahierwerk auf Addition eingestellt ist und addiert wird und in der betreffenden Dekade der Ausgang (y) H-Potential hatte. Auch bei Subtraktion wird dieses Parallel-Addier-Subtrahierwerk nach Figur 8 durchgesteuert, wodurch in den Dekaden, welche an ihrem Ausgang (y) H-Potential hatten, im Anschluß noch die Zahl 6 (LHHL) subtrahiert wird.

Title: Process for absorbing sulphuric acid in flue gases
Inventor: ASTBERG AAKE
IPC: B01D53/48
Filed: 1983-08-23
Abstract: A process for absorbing sulphuric acid in flue gases by admixing a particulate absorbent such as, preferably, finely ground lime powder to the flue gases which are fed to a heat exchanger to cool them comprises, according to the invention, spraying the absorbent into the flue gases in a defined zone upstream of the heat exchanger and thoroughly mixing the absorbent with the flue gases, the absorbent having a sufficiently low temperature to form a cloud of relatively cold particles which are uniformly distributed and act as nuclei of condensation to precipitate the sulphuric acid prior to coming into contact with the heat exchanger. As a result, corrosion phenomena and blockage of the heat exchanger are substantially avoided and the constructional costs therefor are considerably reduced. The mixture of flue gases and absorbent is expediently subjected to intensive infrasonic vibrations during the flow to and through the heat exchanger, as a result of which the admixture is promoted and permanent precipitates in the heat exchanger are prevented.

Patent DE-3332658-A1 (DE)
Title: Latching spring
Inventor: KOELLING DIETER
IPC: F16B21/08
Filed: 1983-09-09
Abstract: The latching spring which can be fitted to any desired component (1) is used for the positively-locking retention of the component on a support (2). The latter is provided with a step (4) behind which a latching tab (6), which is fitted to the end of the latching spring, falls. The latching spring consists of two latching spring strips which are guided parallel and are connected to one another in the region of the latching tab (6) and of a cut-free tongue (9) which is connected there to the latching spring strips and to the latching tab. The tongue is constructed to have a stable shape over its entire length and, at its free end, has a lever (11) via which the latching tab (6) which has fallen into the step (4) can be pivoted out of the step region by hand. In this case, the latching spring is elastically deformed over the entire length of the latching spring strips, the spring force being distributed approximately uniformly over the spring path. Possible bending of the spring as a result of swivelling about a rotation axis is thus prevented. The invention is particularly suitable for fixing small components to a support, for example for fixing distributors, switches, relays and the like to a supporting frame. <IMAGE>
